Low Carb and Dairy Free - What do I eat?

I'd stick with mostly vegetables and meats. 50 net carbs is pretty low so you are not going to have much room for grains.

You can try soy, almond, oat, rice or coconut milk as a substitute for milk. There are soy substitutes for cheese and yogurt, but I've never tasted them.

I agree about the dr telling you "no carbs at all" because in my experience unless you eat only meat and fish its impossible, everything has carb - fruit, veggie, dairy, etc.

I think it possible to go cow dairy free but it would be hard. If your not allergic to nuts then yes you can eat soy/ tofu, edemame, plenty of fruits and veggies and as for milk almond/ soy and other alternatives are fine. I will warn that some of the "cheese" alternatives are plain nasty though lol. But you can also eat meat and eggs so there are options.

Low carb sucks but there are good treats and alternatives out there you just have to find them and try util you find what works for you.

I love Goat Cheese and Feta made from goats milk. Both are available at the local grocery, but I buy them in bulk (Goat Cheese at Costco and Feta from Whole Foods).

I have seen goat's milk yogurt but I do not know how it tastes.

You could ask your local grocery to stock these products if you do not find them on your own.

Stop eating dairy entirely, it causes so many problems! If you want a milk substitute, I recommend Flax Milk. I buy the brand Good Karma.

Dairy Milk causes weight gain: Contrary to what you have been told, milk will actually make you fatter instead of losing weight. If you are in the habit of drinking milk frequently, it is not shocking that you have become overweight. As you drink more and more milk, you will gain more and more weight.

Milk causes a host of other diseases: Besides weight gain, there are a lot of harmful side effects of drinking milk, such as arthritis, constipation, skin allergies, cancer, acne, etc

Now that's a load of codswallop. Crazy...

Almond milk is a good substitute for dairy.

You can even make your own almond or cashew cream.

So, I am a low-carb, ovo-vegetarian... This means, I don't eat any dairy, but consume eggs. I made this change a few months ago, when I noticed that, while consuming a vegan diet (upwards of 130 to 200 carbs a day), I was having major fatigue issues. As in, two hours after breakfast, I wanted to curl up and go to bed, and every afternoon on my way too the gym, I wanted to fall asleep and was foraging for caffeine and a granola bar pick me up. The Crash and Burn was an everyday occurrence for me. I was downing coffee, in hopes of a boost, but it was doing little to nothing for me. So, I decaffeinated for two weeks, and was still experiencing major fatigue, naturally. I pushed back the coffee, to my one cup a day, always at breakfast... and found that I was still tired. I knew I had to change something. Aside from that last 15 pounds I just could not seem to get back off. I felt horrible ALL the time. So, I came across Atkins, the new Eco-Atkins, customizable for vegans and vegetarians. I can't/don't want to eat dairy, and I morally can't get behind the high dairy consumption. But, I made the egg compromise, to no more than one a day (organic, steroid and hormone free, cage free eggs for me only). That seems fair, and healthy to me. I feel so much better. I have sustained energy, and feel so light and good. Like I've got my spark back. I've been eating LOTS of non-starchy vegetables, and a nice balance of tofu (1 net carb per serving), seitan (which I make weekly at home, super easy, 4 net carbs per serving), and eggs(<1 net carb per serving). Along with the right amount of fat to make up for the reduction in carbs, this helps the body produce sustainable energy and fight off hunger and cravings. Such as avocados, olives, artichokes, olive oil, and coconut oil. I am getting complete proteins this way, good fats and plenty of nutrients. Remember you do not have to complete the protein at the meal, just some time within that day. Along side the reduction, of carbs, I've cut out sugar... and that's helped with my bladder infections (perk). I occasionally have a sugar free low carb protein shake, and tofu is sooo versatile. I make tofu scrambles when I am not up for an egg. Vegetarian protein has really come a long way. I consume about 30 net carbs a day now, so I know that 50 net carbs a day is completely do-able. At 50 net carbs a day you can have some grains, nuts, fruits... really your options are pretty versatile.
I highly recommend looking into it... It may take a few weeks for your body to adjust to the new dietary change, but once you're past that... you should feel great. This has been the easiest diet I have ever been on, and I HATE diets. Plus, I've taken of 5 lbs, just this month.
I mean, my path isn't perfect for everyone, but do what's best for you. Anything is possible.

OP I had a blood test done many years back and it showed I have the exact same allergy to dairy as you. Mine caused sinus headaches. I still have some but not too much and I'm fine. Goats milk and it's cheese/yogurt as mentioned before is a good substitute. What are your symptoms from the dairy? Don't think you mentioned unless I missed it.

Edited to say ok you said allergies but what sort exactly?
